Gastank Sweden AB (Pitea, Sweden) reported on Feb. 27 that it has obtained type certificate according to UN ECE R110 regulation for its new Type IV compressed natural gas (CNG) cylinders for motor vehicles. Using Dow’s (Midland, Mich., USA) composite resin technology with HiPer-tex glass fiber from 3B (Battice, Belgium), Gastank Sweden AB offers high-performing and cost effective pressurized gas cylinders to automotive, commercial transportation, and industrial areas.
VORAFORCE TW toughened epoxy systems from Dow are designed to enable production of lightweight and durable composite cylinders with improved impact resistance, dynamic fatigue and low-temperature performance.
Professor Kurt Berglund, president of Gastank Sweden AB, states: “During several tests, the toughened epoxy systems from Dow showed excellent fiber wetting, reduced waste and gave high-quality final properties of the cylinders. Thanks to the long open time and features, the Dow solution allowed Gastank to optimize the winding process and fasten production, making our CNG cylinder solutions even more attractive to the industry.” Satisfied with these results and the successful UN ECE R110 qualification, Berglund has expressed plans to pursue new projects with the Dow technology.
“In times when demand for natural gas vehicles is growing fast, Dow responds to the needs of the industry for light, strong and durable composite pressure vessels that enable better mileage and reduced emissions, replacing traditional metal cylinder tanks,” comments Francesca Pignagnoli, EMEA market manager for Industrial Composites at Dow.
